Drum to Disc MC Issues
‘68 Barracuda. Pulled the factory drum/drum MC to replace it with a new drum/disc unit for my front disc conversion. The forum recommends the Raybestos MC36406 as this a non power assist swap and this MC has the desired 15/16” bore. (This thing is huge compared to the original!)
However, the new master has no provision to retain the new dust boot. Suppose I could drill and tap it to transfer the old retainer but that seems like a goofy solution. Any recommendations? Put the boot on the rod, shove it as forward as possible and call it good enough?
Second issue, is there supposed to be a return spring on the rod? Didn’t find one when I took the MC off, but I’ve seen diagrams with and without one.
Lastly, the bolt/nut holding the pedal to the rod is a major pain to get to and remove. Halfway through unthreading it, I was seriously wondering how in the heck I would get it back in there. So, I opted to put some wood between the MC and the firewall and yank on the pedal to separate the rod from the MC. My question is; can I reinstall the rod and boot by just guiding the rod into the back of the MC and just pushing hard while a buddy holds the brake pedal down? Or do I still need to take the rod all the way out and do it on the bench?
Never done this before, so figuring it out as I go. Last tricky bit is going to be replacing the distribution block with a combo one. There is VERY limited room to work in there.
Thanks for any advice and insight!
